This guide explains how to build Krita from standard Qt 5 and KDE Frameworks 5 development packages provided with your favorite linux distribution.  Building Krita is fundamentally [https://community.kde.org/Calligra/Building/3 similiar to building Calligra], but there are a few differences. I am too lazy to copy all of those instructions into this page, it would be nice if you did it though. <tt>=)</tt>
 
 
 
=== Debian/Ubuntu dependencies ===
 
Here are the names of Krita's dependencies in the Debian repositories.
 
 
 
sudo apt install extra-cmake-modules  libkf5archive-dev libkf5completion-dev libkf5config-dev
 
libkf5coreaddons-dev libkf5guiaddons-dev libkf5i18n-dev libkf5itemmodels-dev libkf5itemviews-dev
 
libkf5widgetsaddons-dev libkf5windowsystem-dev libkf5kiocore5 qtbase5-dev libqt5svg5-dev
 
qtdeclarative5-dev libqt5x11extras5-dev libqt5opengl5-dev libeigen3-dev libxi-dev libboost-all-dev
 
libopenexr-dev vc-dev libexiv2-dev libgsl0-dev liblcms2-dev libpoppler-qt5-dev shared-mime-info
 
libraw-dev libfftw3-dev libopencolorio-dev libcurl-dev libopenjpeg-dev
 
 
 
=== Arch Linux dependencies ===
 
 
 
Building Krita 3.x on Arch requires slightly more dependencies than running 2.9.9; this should get you going (90% of these are 2.9.9 dependencies already):
 
 
 
''Note: these seem to include the Qt4/KF4 dependencies of Krita 2.9. Could someone remove the unnecessary ones?''
 
 
 
sudo pacman -S attica-qt4 qca-qt4 libdbusmenu-qt4 polkit-qt4 exiv2 strigi docbook-xml
 
docbook-xsl libplist libusbmuxd libimobiledevice upower libatasmart udisks2
 
cdparanoia libvisual gst-plugins-base phonon-qt4-gstreamer libqzeitgeist

== Building Krita ==
 
Once you have installed the dependencies, you are ready to clone the Krita repository.
 
 
 
cd ~/kf5/src              (Or, wherever you want to download the source code)
 
git clone git://anongit.kde.org/krita
 
 
 
 
 
=== CMake commands ===
 
Krita's build system has diverged from the Calligra build system and will continue to do so.  For example, since there is only one product, Krita does not use productsets any longer.  For your initial build of Krita, you probably don't want to run the tests. <tt>RelWithDebInfo</tt> optimization level is nearly always good enough for everyday debugging, but it is also fast enough to paint with.  <tt>=)</tt>
 
 
 
This will create a directory <tt>~/kf5/</tt> for KDE Frameworks.  The final installation directory for Krita will be <tt>~/kf5/inst/bin/krita</tt>.
 
 
 
cd ~/kf5/build/krita
 
cmake ~/kf5/src/krita -DCMAKE_INSTALL_PREFIX=~/kf5/inst -DCMAKE_BUILD_TYPE=RelWithDebInfo -DBUILD_TESTING=OFF
 
make -j8
 
make install -j8
 
 
 
 
 
Remember that you can change build settings with <tt>cmake . -DNEW_SETTING</tt>  or by using <tt>cmake-gui</tt> found in the package <tt>cmake-qt-gui</tt>
 
 
 
== Environment variables ==
 
'''XDG_DATA_DIRS.''' You need only one environment variable to run Krita 3:
 
export XDG_DATA_DIRS=~/kf5/inst/share:$XDG_DATA_DIRS
 
 
 
'''KRITA_PLUGIN_PATH.''' Currently, running inside a debugger can be a bit fragile due to plugin loading.  Krita's plugins are built in several different paths inside the source directory, and the installation process copies them into a single folder. However the debugger might accidentally not catch onto the plugin installation directory. (For example, if it thinks the plugin path is <tt>./build/krita/plugins/</tt> then it will miss the plugins contained in <tt>./build/plugins/</tt>.  It may be possible in the future to fix this by altering Krita's codebase, but such large changes are not yet possible until the break with Calligra repo is more complete.)
 
 
 
You can force Krita to look in a specific folder for plugins using the environment variable <tt>KRITA_PLUGIN_PATH</tt>.  For example, using Kubuntu and installing Krita in ~/, I can use a debugger if I set the environment variable:
 
export KRITA_PLUGIN_PATH="~/kf5/inst/lib/x86_64-linux-gnu"
 
 
 
'''QT_MESSAGE_FORMAT''' and '''QT_LOGGING_RULES'''
 
See <tt>main.cc</tt> and http://woboq.com/blog/nice-debug-output-with-qt.html
